Devrom® is an internal deodorant. It is an OTC (over-the-counter) medicine taken orally (chewed or swallowed) to neutralize odor from flatulence and stool. FDA approved and recommended by doctors, pharmacists and nurses nationwide, Devrom® is an inexpensive but effective treatment for malodor. Devrom® helps people regain their dignity from embarrassing and sometimes debilitating flatus odor.
